The IUPAC was formed in 1919 by scientists and academicians who recognized a need for standardization in chemistry. The predecessor of the IUPAC, the International Association of Chemical Societies (IACS), met in Paris in 1911 to propose issues that needed to be addressed. From the beginning, the organization has sought international cooperation between chemists. In addition to setting guidelines, the IUPAC sometimes helps to resolve disputes. An example is the decision to use the name 'sulfur' instead of both 'sulfur' and 'sulphur'.
